Everything you believe about how to lose weight is wrong. Weight gain and obesity are driven by hormones and only by understanding the effects of insulin and insulin resistance can we achieve lasting weight loss. Both obesity and Type II diabetes are diseases caused by excessive insulin. There are five basic steps in weight loss: Reduce your consumption of added sugars. Reduce your consumption of refined grains. Increase your consumption of natural fats - there is no association between dietary fat and obesity. Increase your consumption of fiber and vinegar. Moderate your protein intake - excessively high protein diets are not advisable. Use intermittent fasting to break the cycle of insulin resistance and reach a healthy weight, for good. Dr. Jason Fung sets out an original, robust theory of obesity with startling insights about proper nutrition. In addition to the five basic steps for weight loss, the book presents a set of lifelong habits that will improve your health and control your insulin levels.
